A WY B A TTORNEY Patented Nov. 6, 1934 o 1,919,974 HARVESTER PICK-UP Wallace F..MacGregor, Racine, Wis., assignor to J. 1. Case Company, Racine, Wis., a corporation Application July 17, 1933, Serial No. 680,683 7 Glaims. (Cl. 56 364) My invention relates to improvements in baling machinery of the character disclosed in Letters Patent No. 1,919,897, issued July 25, 1933, by which I am enabled as conditions require to either draw the machinery through a field and pick up windrowed hay from the ground and convey it to the baler, or position the machinery adjacent a stack or pile and load the material onto a pick-up to be conveyed to a baler, the actuating means for the pick-up during the first operation being ground driven, and for operation in a stationary position the ground drive is dispensed with and the pick-up actuated by power from the baler or other source as will hereinafter more fully appear.

In the accompanying drawing, forming a part hereof, Figure l is a plan view of a combination baler and pick-up embodying my invention; Fig. 2, a side elevation thereof; and Fig. 3 a fragmentary side elevation taken on the dotted line 3-3 in Fig. 1.

In said drawing it will be understood from Fig. 1 that the combination baler 5, pick-up 6, and cross conveyor '1, may be drawn through a field and the mechanism thereof actuated by a tractor 8 having a power take-off shaft 9 connected to the baler, but it will be understood that any suitable driving power may be employed.

The baler 5 is in part secured to and supported by a rocking axle 10 carried by the wheels 11,

v 12, the latter wheel 12 being extended in relation to the baler for supporting the pick-up, the baler, as is common, comprising a suitable body embodying a baling chamber 13 in which material is inserted by the feeder head 14 of any desired construction, and compressed by a plunger (not shown);

The pick-up comprises a body 15 having shoes 15' in which body is mounted a carrier formed of chains 16 connected by cross slats 1'7, and which chains travel about a floor 16', thence over upper sprockets 18 mounted on shaft 19, and also over lower sprockets 21 mounted on shaft 22, said sprockets 21 carrying shafts 23 upon which tines or fingers 24 are supported to revolve with these sprockets. At the upper end of the carrier a roller 20 is mounted and driven by a chain, as 20', and other details of construction are embodied in the carrier but being no part of my present invention need not be specifically described herein. V

The pick-up is pivotally mounted on axle 10 by means of a push-bar 26 and standard 2'7, the

latter carrying a bracket 28 supporting a tightto the baler 5, the

ener 29 for controlling a chain 30 connecting a sprocket 31 on the wheel 12 to the sprocket 32 in the pick-up loosely mounted on a shaft 33 having a sprocket 34 at each end engaging the respective chains 16 for driving the direction indicated by the arrow in Fig. 1. Said shaft 33 at itsinner end is provided with a sprocket 35 connected to sprocket 36 on a drive shaft 37 by a chain 38, which latter shaft is also geared at 39 to the cross conveyor 7, shaft 37 in turn being connected at 41 to a drive shaft 42 actuated by any suitable power such as a tractor or otherwise whereby the carrier and cross conveyor may be operated.

Vertical adjustment of the pick-up may accomplished by a lever and quadrant 43, 44, located at any convenient place on the baler, towhich a rod 45 is secured and at its opposite end is slidably attached to an arm '46, springs 47, 48, being retainedon said rod at opposite sides of the arm 46 so that when said rod is adjusted longitudinally it will be held in locked position by the lever and quadrant to hold the pick-up at the desired elevation.

As indicated, the machine in general the carrier in 69 said includes 80 the details of construction and arrangement dis- 37 so that chain 38 may be removed from sprockets 35, 36, and upon returning the carrier to full line position and engaging slip-clutch members 50 the sprocket-and- chain system 30, 31, 32, through the ground wheel 12, will actuate the pick-up carrier and anisms to gather material while the machinery is moving through the field and deliver the same to the cross conveyor '7 to be conveyed thereby cross conveyor, as will be understood, being actuated from shaft 37. When it is desired to operate the baling machinery in stationary position adjacent a stack 01' pile of material the carrier is adjusted to the position shown in dotted line, Figs. 2 and 3, and the chain replaced, which movement throws the sprockets 35, 36, into the position shown in full lines in Fig.3, thus drawing said chain taut thereabout, and upon disengaging clutch 50 to render the ground drive inoperative the carrier and cross conveyor will be actuated by the associated mechscribed it will be seen stacks and the like.

5 disruption of the means and said shaft for shafts 33, 37, so that the material may be loaded onto the carrier to be conveyed by it and the cross conveyor to the baling machine to be baled. In the simple manner shown and dethat the machinery may ,be readily converted into a traveling ground driven outfit for gathering material in its path to be baled, and as readily adjusted for operation stationarily when it is desired to bale from And it will also be understood that when in working position as indicated in full lines, Fig. 2, the runners 15 of the pick-up will so stabilize said structure and parts associated therewith as to prevent straining or gear systems forming part of the machinery.

I claim as my invention:

1. In a machine of the class described, the combination, with a wheeled support, of means for gathering and elevating cut material from the ground, ground driven means associated with and actuating the gathering means while the latter is traveling, means for rendering said driven means inoperative, means for conveying material from the gathering means, means for receiving material from the conveying means, and means associated with the conveying, receiving and gathering means for actuating the gathering means when the latter is in stationary position.
